Abstract
The utility model discloses a profiling cam shaft grinding machine head bracket, comprising a motor, a rocker shaft (2), a profiling (3) and a profiling shaft (4), the profiling (3) is arranged on the profiling shaft (4), and the motor is connected with the profiling shaft (4) by a decelerating transmission device. By adopting the technical proposal, the transmission torque is increased, the bracket can lead the surface of the cam ground to be smooth, the size precision and fineness are improved, and the abrasive resistance of the cam shaft is enhanced.
Description
Technical field
The utility model relates to a kind of grinding machine headstock, particularly a kind of master cam travelling wheelhead roll grinder headstock.
Background technology
At present, utilization profile tracer method is carried out in the process of grinding cam in grinding machine, be to be connected between motor and the profiled shaft initiatively by shaft coupling, and all be to adopt stepper motor or servo digital control motor as the active motor of drive unit, do like this and just have following deficiency: because it is very big to drive the moment of torsion of profiled shaft rotation, and it is, very high to the performance requirement of drive motors because cam makes the driving torque excursion bigger for abnormity; Because it is very hard that the characteristic of stepper motor or servo digital control motor can not be done, so stepper motor or servo digital control Motor torque are big inadequately, cause the rotation of profiled shaft inhomogeneous, particularly stepper motor or the moment of torsion of servo digital control motor when slowly running are more inhomogeneous, it is inhomogeneous so more can to cause profiled shaft to rotate, cam face ripple and chatter mark that its grinding is come out are bigger, thereby influence the result of use of cam, have directly influenced the service behaviours such as stroke of cam.
Summary of the invention
The purpose of this utility model just provides a kind of master cam travelling wheelhead roll grinder headstock that can increase driving torque.
The purpose of this utility model is to realize that by following technical scheme it includes motor, reel cage axle, pattern and profiled shaft, and pattern is arranged on the profiled shaft, and described motor is connected with profiled shaft by speed reduction gearing.
Described speed reduction gearing comprises driving pulley, the driven pulley that is connected with profiled shaft that is connected with electric machine main shaft and is used for the transmission of power of driving pulley is arrived the synchronous belt of driven pulley.
The utility model is work like this: motor is arranged on the reel cage axle, the motor-driven driving pulley is rotated, the rotation of driving pulley drives the driven pulley rotation by synchronous belt, the driven pulley rotation drives the profiled shaft rotation, the rotation of profiled shaft drives the pattern rotation again, because pattern contacts with fixed roller, pattern drive profiled shaft produces around the reel cage axle and waves, thereby make the cam of processing to be ground be imitated the type grinding, obtain the shape of technological requirement according to the contour shape of its roller.
In order to reach better deceleration effect, described speed reduction gearing is the one-level transmission, and its diameter of driving pulley that is used for power output is less than the diameter of the driven pulley that is used for the power input.
More even and steady for the power that makes transmission, in the axis hole of driven pulley, be provided with connecting axle, described connecting axle is connected with profiled shaft by shaft coupling.
In order to prevent to occur skidding between synchronous cog belt and driving pulley or the driven pulley, described synchronous belt is a synchronous cog belt.
Owing to adopted technique scheme, the utlity model has following advantage:
1. adopt the one-level speed reduction gearing, increased the moment of torsion that motor is delivered to profiled shaft, make that the rotating speed of profiled shaft is even, the cam face that grinding is come out is smooth, and dimensional accuracy and fineness are improved, and have strengthened the wearability of camshaft;
2. employing double reduction gear can further improve the moment of torsion that motor is delivered to profiled shaft;
3. because the driving pulley diameter is bigger than driven pulley diameter, do to obtain very high speed reducing ratio like this, profiled shaft can increase exponentially driving torque;
4. the employing shaft coupling makes the power that transmits more evenly with steady;
5. employing synchronous cog belt does having prevented the phenomenon that occurs skidding between synchronous cog belt and driving pulley or the driven pulley like this.
Description of drawings
Description of drawings of the present utility model is as follows:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
Embodiment 1, and as shown in Figure 1, 2, the utility model includes motor, reel cage axle 2, pattern 3 and profiled shaft 4, and pattern 3 is arranged on the profiled shaft 4, and described motor is connected with profiled shaft 4 by speed reduction gearing.
Described speed reduction gearing comprises driving pulley 5, the driven pulley 6 that is connected with profiled shaft 4 that is connected with electric machine main shaft and is used for the transmission of power of driving pulley is arrived the synchronous belt 7 of driven pulley.
The utility model is work like this: motor-driven driving pulley 5 is rotated, the rotation of driving pulley 5 drives driven pulley 6 rotations by synchronous belt 7, driven pulley 6 rotations drive profiled shaft 4 rotations, the rotation of profiled shaft 4 drives pattern 3 rotations again, because pattern 3 contacts with fixed roller 9, pattern 3 drive profiled shafts 4 produce around reel cage axle 2 and wave, thereby make the cam of processing to be ground be imitated the type grinding, obtain the shape of technological requirement according to the contour shape of its roller.
In order to reach better deceleration effect, described speed reduction gearing is the one-level transmission, and its diameter of driving pulley 5 that is used for power output is less than the diameter of the driven pulley 6 that is used for the power input.
More even and steady for the power that makes transmission, in the axis hole of driven pulley 6, be provided with connecting axle 1, described connecting axle 1 is connected with profiled shaft 4 by shaft coupling 8.
Described synchronous belt 7 is a synchronous cog belt, and the purpose of doing like this is to occur skidding between synchronous cog belt and driving pulley 5 or the driven pulley 6 in order to prevent.
The utility model includes but not limited to the above specific embodiment, all drops in the protection domain of the present utility model as long as be provided with speed reduction gearing between motor and profiled shaft.
